Great work! Just one thing missing: the dds files must be saved generating mip-maps. That´s why the cars look blurry.

The skins were not mine, I only reported the blur issue I had.
The good news is that your solution works, blur in previews is gone now, so thanks for the tip 👍

Another adaptation completed to make up the grid (Le Mans in the 60s), Maserati Tipo 63 (used as a basis for the Maserati Tipo 61 by Adalexis).
It wasn't 100% the same, until someone decided to make a more accurate model. We'll be heading to on-track testing for one (BoP) soon.

6- Briggs Cunningham - Bruce Mclaren / Walt Hansgen
7- Briggs Cunningham - Augie Pabst / Richard Thompson
9- Scuderia Serenissima - Ludovico Scarfiotti / Nino Vaccarella

I decided to adapt the model again (I think it was a little better)

Looks like a mix-up between a Birdcage and a Ford P68, right ?

@JK1977 now that's a fat boy ! Looking really cool

@Peter Boese, let us know here, when you release this “Fog” pure
Normally, I prefer to spent all my adjustments in CM to shimmer eliminating and a frame rate to 90fps straight, so my AC is lean, without any addons nor external injectors, like PURE/PPfilters or whatever that have influence on my ideal VR view. Only with that fog PURE, I see some potential to reduce all the distance shimmer and other visual artifacts even more, which are always for me a massive immersion killer in VR.

New livery skin for the Nissan R32 JTCC "AIM Motorsports" (WIP)

you will not solve any of that graphics problems with that fog shader to be honest. Those graphics problems are caused by the VR renderer and how good it utilizes AA and in which render resolution you render the original image. There are big differences between the hmd renderes. Like the one WMR is using, the picture quality is really good and such aliasing is not a big problem there, whereas with the oculus renderer there is a really bad picture quality in normal resolutions.

I just did a direct comparison between the HP Reverb G2 (WMR) and the Meta Quest 3 (Oculus - cable) and the "shimmer" or better called "aliasing jitter" is very minor in the G2 but huge in the Quest.

So sure fog could solve this, but only because you just have no objects / contrast in the renderer then.

One thing you can also do is gaining the mip lod bias. This will prevent high detail in those "line" or stait textures/objects:

Just an exaggerated example:

So distant objects will sooner use lower mips and so the textures become more blurry and the aliasing jitter is therefore way lower.


Another fog solution you can do is lower the fog distance of the track then, like here in Pure Config:

When gaining the FOG_SHAPE, the AC fog gets less distance and will so mask such objects, but with all resulting visual downgrades in view distance.

 

[Quark67]

After a HD failure I could recover almost everything (with a great help from @Breathe... THX again), except
legens1 font and fcr_kopecky driver.

I have to check in which of the thousand of cars mod they are.
Is there a way to know which car has the issue when CM displays the missing fonts (or drivers) after pressing "Rescan" under "Content\Miscellaneous" menù?

You mean the Thai script below the TOTAL logo, right?
That translates as "Various World Sports" which I'd guess is a best-guess translation for "World Wide Sports". The "9" logo is likely a TV station/channel logo. So...

A big thanks for clarifying, indeed I do prefer blurred images more then shimmering and have absolutely no problem in hiding those shimmering objects by fog. That shimmering also depends on the circuit or creator. Those converted from old racegames are mostly the worst.
About WMR, you are aware that’s Microsoft will abandon WMR? So I guess after a time I’m forced to exchange my WMR headset to the Pico4 or the Quest3, because these are the only “budget” friendly headsets available.

i can confirm the front is from a P68 and there is a Lotus 23 rear on it aswel

Good morning. You know everything.
Front: Ford P68 (changing the x-y-z dimensions a little)
Rear: Lotus 23 (I "copied" the same piece 3 times, in slightly different scales).
Windshield: Jaguar xj13 (also with changes to the x-y-z scale)

i look closely at the cars you adapt and find out what you used, like in the 1965 Spitfire i found the 1970's spitfire rlly small just above the rear wheel arches

Hi Team,

I have a VRC 2007 car and it seems the driver head looks down when viewed from a larger distance and suddenly pops to normal when the car gets closer to the camera.

I have tried to change driver model, but this look down far away, look up closer feature is there with all models. If I save driver pos or save KNH in CM then driver always looks down even if car is close, but it also looks ugly. Also tied to modify high res driver and high res cockpit distance in data.acd, but no luck.

Ferrari driver looks down:

Ferrari driver looks "up":

Do you have an idea how to fix this?
Car is VRC 2007 and LODs are encrypted.

You have wrong settings on CM. You need to allow season adjustment

I have changed the tarmac to sand, only now in the distance the sand is looking pale, while at near view the colour is perfect. How to solve this?

Damn, new CSP linear Color Space breaks almost all of the mod-cars in my library (makes them ugly) but I see the potential with this Kunos car, especially at night:

"Old" Pure weather-style:



New CSP Linear Color space


( I only changed the weather style, nothing else was changed in these pictures. )
I just hope for Peter that he doesn't have to start all-over again because of this...


EDIT: For now it seems like the cars that are well-built become more beautiful, and the cars that are meh-built, start showing some cracks when turning Linear Color Space on. But Ilja said we should have patience, he's not done updating the feature just yet.

 

[arctx]

This is no distant fog. It creates fog billboards in the near of your camera. And in its default settings its very efficient, because it uses th AI spline to place them. So it realy depends on the settings, but i tried to keep the CPU and GPU usage as low as possible due to many optimizations.

here is a comparison on and off:
View attachment 1343593

View attachment 1343594


It also depends on the tracks. so for small trakcs, you will see a lot of those billboards, because you already see billboards of the incoming spline. But for long tracks you will only have like a corridor where you move along some single road. But therefore you have more billboards on those long tracks.

Hey Peter. This is great news ! I remember some time ago (years maybe,... yeah in 2022 ) we talked about this on discord, implementing fog and how to, back then I played/tried with smoke effects to make fog patches . I waited 2 years for this. It is quite nice for start! I liked the video. But what I was expecting with great enthusiasm didn't come yet. Specifically, you never feel that you enter the fog. Your visibility never changes, you dont get inside that fog and looking around its not there, the car ahead remains visible in the same amount, like this effect always goes fixed in front of the car but you never really get in it/go through it. I expect when going in a fog patch to loose some visibility depending on the density/size of that fog patch. That doesn't happen yet with this implementation. I hope there is a way to implement this better. But its a nice start !!! Cant wait to try it.

 

[X90]

anyone got a changelog link for the new CSP preview? Want to know if the AI starting bug is fixed before resubscribing.


EDIT: It looks like the AI not starting is indeed fixed with this preview release. I'm also interested to see how this "multithreading Extended Physics" might work - I've been CPU-limited before on my 9900K with more than 20 RSS cars on screen at starts. Wonder if that changes.

Looks to be worth the resubscription.

To me the second pic looks more realistic and therefor better. (but Des goûts et des couleurs...)

  • Kunos cubic interpolation LUTs (tyre load sensitivity and camber LUTs) no longer extrapolate (caused numerous issues for modders over the years including unexplained explosions and game crashes);

  • Debug lines use exact joint positions;
• Tyres:
  • Thermal Model v2 is supported (docs are coming soon);
  • Better edge-case contact normal calculation (limits contact normals to some threshold from tire radial normal; should avoid strange load spikes and other edge-case phenomena where rays contact the surface strangely);

• Issues with AIs driving worse or choosing wrong AI spline (recent CSP regression) fixed;
• Timezone sanity fix updated;
• YEBIS: setting exposure to 0 works (making screen black, but it beats ignoring the change switching to 0% and leading to unpredictable behavior);
